RESUMEN
Aeromonas lusitana sp. nov. is an isolate derived from a study aimed at characterizing Aeromonas spp. from water sources used for recreation and agricultural purposes and assessing the implications these organisms have for human and animal health. We present here the 4.52-Mbp draft genome sequence of this novel species.
RESUMEN
Species of the Aeromonas genus can be found in numerous environmental milieus, including various water sources, and some species cause disease in animals. We present here the draft genome sequence for Aeromonas cavernicola DSM 24474T, a novel species isolated from a freshwater brook within a cavern in the Czech Republic.
RESUMEN
A new diffractometer has been built with which energy-dispersive diffraction patterns can be collected simultaneously at different angles. The first use of this system for dynamic (time-resolved) studies--the hydration of cements under various conditions--is reported. It is found that the optimization available with a three-element detector system enables collection of high-quality patterns over a much wider and more effective range of reciprocal space, and this yields improved and new information on the hydration processes.
RESUMEN
A review is given of the results and lessons arising from a sustained in situ diffraction study of the structure and performance of functional ceramic/cementitious materials in which synchrotron-based energy-dispersive diffraction has been the central under-pinning technique. Five particular points of discussion emerge: the demands on time resolution; the use of penetrating radiation for the in situ mode; the need for complementary techniques; re-analysing of data; spatially resolved diffraction: a new tomography. These aspects are discussed in turn using illustrative examples taken from the fields of cement hydration, clay intercalation, cation-exchanged zeolites, and particulate/fluid invasion into building and archaeological objects.
